Abstract

An apparatus for producing continuous tortillas which includes a double-press system with three conveyors. The two presses are arranged in series to eliminate production gaps as the tortillas proceed into the oven. The structure of the second press is positioned higher than the structure of the first press so that tortillas formed from the second press can be deposited on the intermediate conveyor with tortillas formed from the first press, thereby providing a continuous supply of tortillas to the oven.

Description

RELATED APPLICATIONS
This application is a continuation-in-part of prior application Ser. No. 08/139,712, filed Oct. 22, 1993, and abandoned, which is based on Mexican Patent application No. 926,103 filed Oct. 23, 1992.
TECHNICAL FIELD
The invention relates to the pressing of tortillas by a double-press system with an intermediate continuous moving conveyor to eliminate production gaps as the tortillas proceed into the oven.
BACKGROUND OF THE INVENTION
At present, the production lines for flour tortillas use only one press. Since the movement in delivering the tortillas from the press to the oven is cyclic, and since this movement should be continuous. The present production line utilizes only one press which results in gaps between each group of shaped tortillas, and thus the capacity of the line is not being suitably utilized.
SUMMARY OF THE INVENTION
The present invention addresses the foregoing problem. In the present invention, instead of a single press, two presses are placed in series along a continuous moving conveyor. In this way, the production obtained from the line is doubled without having to install a separate, complete production line. Furthermore, the arrangement of presses in series utilizes the capacity of the machines more efficiently. This makes the equipment more profitable since the production costs decline in proportion to the reduction of space occupied by two single-press lines.
The present invention relates to a production line for flour tortillas. The production line has a mixer for mixing the flour into dough. From the mixer the dough is conveyed to a shaper for shaping the mixed dough into separate units. A positioner receives the dough for further processing. A set of conduits transport the dough from the postioner to a first and second conveyor. The first conveyor receives a portion of the dough units and conveys this dough into a first press wherein the dough is pressed into a flat tortilia. Likewise, the second conveyor receives a second portion of the dough units and conveys this dough into a second press wherein the dough is pressed into a flat tortilla.
The first and second conveyors are synchronized with a third conveyor so that a continuous array of tortillas are supplied to the third conveyor. The third conveyor is positioned below the first and second conveyors and receives pressed tortillas from the synchronized first and second conveyors. The third conveyors transports the continuous array of tortillas to an oven for cooking. The cooked tortillas continue along the production line to a cooler. After the tortillas are cooled, they are transported to a piler which stacks and counts the tortillas. Finally, the stacked tortillas are packaged by a bagger.
BRIEF DESCRIPTION OF THE DRAWINGS
A more complete understanding of the invention may be had by reference to the following detailed description when taken in conjunction with the accompanying Drawings, in which:
FIG. 1 and FIG. 1A are the top and side views of the double-press system in accordance with the present invention;
FIG. 2 and FIG. 2A are the top and side views of the complete production line with the double-press system showing the arrangement of the tortillas; and
FIG. 3 and FIG. 3A are the top and side views of the complete production line with one press (prior art), showing the arrangement of the tortillas.
DETAILED DESCRIPTION OF THE DRAWINGS
Referring to FIG. 1, the present system is made up of two presses (A and B) in series with each other and each having individual conveyor belts and a continuous moving conveyor (C) onto which the tortillas (D) are delivered in a synchronized manner. On the other hand, press (B) is very similar to press (A), except that its structure is higher so that the conveyor (C) passes under the press (B).
Referring now to FIGS. 2, 2A, 3, and 3A, FIGS. 2 and 2A illustrate the present invention and FIGS. 3 and 3A represent the prior art production lines. FIGS. 2, 2A, 3 and 3A show that both production lines have a mixer (2.1 and 3.1), a divider/ball shaper (2.2 and 3.2), a positioner (2.3 and 3.3), a pressing system (2.4 and 3.4), an oven (2.5 and 3.5), a cooler (2.6 and 3.6), a counter-piling device (2.7 and 3.7), and a bagger (2.8 and 3.6); however, if the arrangement of the tortillas (D) is noted, one can see that in a single-press line, very large gaps are left between each group of tortillas (D), which results in a production equal to half the capacity of the double-press line.
The production line for tortillas that include the double-press system operates in the following manner: the flour is prepared in the mixer (2.1), from which it emerges in the form of dough and moves toward a divider/ball shaper (2.2), where the dough is divided into small portions, which after being shaped into balls, passes to a positioner (2.3), from which the dough will fall through some conduits (E) to the pressing system (2.4), which operates in the following manner: the little balls of dough fall onto resting conveyor belts of the presses (A and B); subsequently, the belts will move, placing the little balls of dough beneath the pressing plate which will form the tortillas upon pressing the little balls of dough; while the pressing takes place, the conveyors of presses A and B remain motionless, and after the tortillas have been shaped, the conveyors, which have been synchronized, continue to move forward in such a manner that the tortillas will be deposited on a third intermediate conveyor (C), which in contrast to the press conveyors, moves continuously just as the rest of the line equipment.
The delivery of the tortillas is carried out in the following manner: the conveyor for press (A) delivers a group of tortillas onto the conveyor (C); after the delivery has been completed, the conveyor for press A and press (A) are motionless and the conveyor (C) which is synchronized with the conveyors of presses (A) and (B) will continue to move in such a manner that a space will be formed and when the conveyor (C) gets to the press (B), a group of tortillas from press (B) will fill the space. In this way, continuity of production is attained. As shown in FIG. 1, the structure of the second press (B) is positioned higher than the structure of the first press (A) so that tortillas formed from the second press (B) can be deposited on the intermediate conveyor (C) with tortillas formed from the first press (A), thereby providing a continuous supply of tortillas to the oven. From the conveyor (C), the tortillas pass to an oven (2.5), where they are cooked; then they pass to a cooler (2.6) and finally, they are stacked and counted in a piling device (2.7) and are packed by the bagger (2.8).
This description is not intended to limit the scope of the invention to the particular form set forth, but is intended to cover such alternatives, modifications, and equivalents as may be included within the scope and spirit of the invention as defined in the appended claims.
